After re-building my engine after head gasket failure, I put it back in yesterday, cranked to circulate oil before starting up, and a cam shaft ceased! ouch.....

So I have taken it all back out (in an hour and half!!) and taken the head off the nearside, where the shaft had ceased. The pistons look okay, no damage and the bores look as before. No scores etc.

Now, if I want to fit STI heads, will I have to change anything else? Will they fit striaght onto my block, and what will it change in performance?

Any help would be great, I cant wait to get it running again.... I think my g/friend is about to leave me!

Thanks
